The purpose of the present project is to develop methodologies appropriate to the description of coastal evolution under a changing climate around the UK. This will be achieved by a combination of improved physical understanding of the coastal system and advanced statistical and numerical techniques. In integrating the detailed modelling of coastal processes into long-term climate prediction, the research outcomes will provide the necessary tools to predict coastal change intime scales ranging from 100s to 100,000s years. The main objectives of the project are summarised as follows:Develop process-based simulations of coastal change using dynamically downscaled global climate around UK coasts. Incorporate human interventions (coastal protection structures) and additional sediment source/sink terms in coastal evolution modelling. Dimensional reduction of morphodynamic loops using improved physical understanding and advanced statistical methods (surrogate modelling, storm sequencing). Provide am improved representation of coastal change in short-term time scales (100s of years) under climate change scenarios obtained from IPCC predictions. Integrate the short-term methodology into long-term predictions (100,000s of years). Quantify the uncertainty in models.This information will provide critical insights regarding the selection and assessment of coastal sites as potential Geological Disposal Facilities and provide a sound basis for assessing their safety in the long term.

本项目的目的是开发适合在英国不断变化的气候下沿海进化的描述的方法。这将通过对沿海系统以及先进的统计和数值技术的身体理解的结合来实现。在将沿海过程的详细建模纳入长期气候预测中时，研究成果将提供必要的工具来预测沿海变化的intime量表，范围从1000到100,000年。该项目的主要目标总结如下：开发基于过程的沿海变化的模拟，使用英国沿海地区动态缩放的全球气候。在沿海进化建模中纳入人工干预措施（沿海保护结构）和其他沉积物来源/下沉条款。使用改进的物理理解和先进的统计方法（替代建模，暴风雨测序）来减少形态学环路。在从IPCC预测中获得的气候变化情景下，提供AM在短期时间尺度（100年）中改善了沿海变化的表示。将短期方法整合到长期预测中（100,000年）。量化模型中的不确定性。此信息将提供有关沿海地点作为潜在地质处置设施的选择和评估的关键见解，并为长期评估其安全性提供了可靠的基础。
